YHG1型(xing)冶金設備標準液壓(ya)缸
Y-HG1型冶(ye)金設備標準液(ye)壓(ya)(ya)缸(gang)，為(wei)雙作(zuo)用(yong)單活塞桿液(ye)壓(ya)(ya)缸(gang)，缸(gang)徑從(cong)40~320mm共有17種規(gui)格(ge)，額定壓(ya)(ya)力為(wei)16MPa，可以帶(dai)緩沖裝(zhuang)置。該系列液(ye)壓(ya)(ya)缸(gang)有13種安(an)裝(zhuang)連(lian)接型式(shi)，除軸向腳架式(shi)外，安(an)裝(zhuang)連(lian)裝(zhuang)尺寸均符(fu)合ISO6021/1-1981的規(gui)定。活塞桿端螺紋(wen)亦符(fu)合GB2350-80的規(gui)定。適用(yong)于工作(zuo)溫(wen)度為(wei)-30C~+80C，工作(zuo)介質(zhi)為(wei)液(ye)壓(ya)(ya)油，乳化液(ye)的冶(ye)金設備（不適用(yong)于磷酸(suan)脂）。
液壓缸結(jie)構基本上可以分為(wei)缸筒和(he)缸蓋(gai)、活塞和(he)活塞桿(gan)、密封裝(zhuang)置(zhi)、緩沖裝(zhuang)置(zhi)和(he)排氣裝(zhuang)置(zhi)五個部分。今天(tian)威海力建小編著重(zhong)帶著大家了(le)解一下缸筒和(he)缸蓋(gai)。
缸筒和缸蓋
一般來說，缸筒和(he)(he)(he)缸蓋的(de)(de)(de)結(jie)(jie)(jie)構(gou)(gou)形(xing)(xing)(xing)式(shi)(shi)和(he)(he)(he)其使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)材料有關。工(gong)(gong)(gong)作壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)(yong)鑄(zhu)鐵；p＜20MPa時，使(shi)用(yong)(yong)(yong)(yong)無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管；p＞20MPa時，使(shi)用(yong)(yong)(yong)(yong)鑄(zhu)鋼(gang)(gang)或(huo)(huo)鍛(duan)鋼(gang)(gang)。法蘭(lan)連(lian)接(jie)式(shi)(shi)，結(jie)(jie)(jie)構(gou)(gou)簡單(dan)，容易加(jia)工(gong)(gong)(gong)，也容易裝(zhuang)拆，但(dan)外(wai)(wai)形(xing)(xing)(xing)尺(chi)寸(cun)和(he)(he)(he)重量(liang)(liang)都(dou)較(jiao)大(da)(da)，常用(yong)(yong)(yong)(yong)于鑄(zhu)鐵制的(de)(de)(de)缸筒上(shang)。半環(huan)連(lian)接(jie)式(shi)(shi)，它(ta)的(de)(de)(de)缸筒壁部因開(kai)了(le)(le)環(huan)形(xing)(xing)(xing)槽而削弱(ruo)了(le)(le)強度，為此有時要(yao)加(jia)厚缸壁，它(ta)容易加(jia)工(gong)(gong)(gong)和(he)(he)(he)裝(zhuang)拆，重量(liang)(liang)較(jiao)輕，常用(yong)(yong)(yong)(yong)于無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管或(huo)(huo)鍛(duan)鋼(gang)(gang)制的(de)(de)(de)缸筒上(shang)。螺紋連(lian)接(jie)式(shi)(shi)，它(ta)的(de)(de)(de)缸筒端部結(jie)(jie)(jie)構(gou)(gou)復雜，外(wai)(wai)徑(jing)加(jia)工(gong)(gong)(gong)時要(yao)求保(bao)證(zheng)內外(wai)(wai)徑(jing)同心(xin)，裝(zhuang)拆要(yao)使(shi)用(yong)(yong)(yong)(yong)工(gong)(gong)(gong)具(ju)，它(ta)的(de)(de)(de)外(wai)(wai)形(xing)(xing)(xing)尺(chi)寸(cun)和(he)(he)(he)重量(liang)(liang)都(dou)較(jiao)小，常用(yong)(yong)(yong)(yong)于無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管或(huo)(huo)鑄(zhu)鋼(gang)(gang)制的(de)(de)(de)缸筒上(shang)。拉(la)桿連(lian)接(jie)式(shi)(shi)，結(jie)(jie)(jie)構(gou)(gou)的(de)(de)(de)通用(yong)(yong)(yong)(yong)性大(da)(da)，容易加(jia)工(gong)(gong)(gong)和(he)(he)(he)裝(zhuang)拆，但(dan)外(wai)(wai)形(xing)(xing)(xing)尺(chi)寸(cun)較(jiao)大(da)(da)，且較(jiao)重。焊接(jie)連(lian)接(jie)式(shi)(shi)，結(jie)(jie)(jie)構(gou)(gou)簡單(dan)，尺(chi)寸(cun)小，但(dan)缸底處內徑(jing)不易加(jia)工(gong)(gong)(gong)，且可(ke)能引起變形(xing)(xing)(xing)。
零部件(jian)加工(gong)精(jing)度(du)(du)(du)(du)的影(ying)響問(wen)題(ti)，在液壓缸的制造過程(cheng)中(zhong)應嚴格控制缸體內(nei)壁和(he)活(huo)塞桿(gan)表(biao)面(mian)加工(gong)精(jing)度(du)(du)(du)(du)，特(te)別是幾何精(jing)度(du)(du)(du)(du)，尤其直(zhi)線(xian)度(du)(du)(du)(du)是關鍵，在國(guo)內(nei)加工(gong)工(gong)藝中(zhong)，活(huo)塞桿(gan)表(biao)面(mian)的加工(gong)基本上是車后磨削(xue)，保證(zheng)直(zhi)線(xian)度(du)(du)(du)(du)問(wen)題(ti)不大，但(dan)(dan)對于缸體內(nei)壁的加工(gong)，其加工(gong)方(fang)法很(hen)多(duo)，有(you)鏜(tang)削(xue)-滾壓、鏜(tang)削(xue)-珩(heng)(heng)磨、直(zhi)接(jie)珩(heng)(heng)磨等，但(dan)(dan)由于國(guo)內(nei)材料的基礎水平較國(guo)外(wai)有(you)差(cha)距，管(guan)(guan)材坯(pi)料直(zhi)線(xian)度(du)(du)(du)(du)差(cha)，壁厚不均勻、硬度(du)(du)(du)(du)不均勻等因素，往(wang)往(wang)直(zhi)接(jie)影(ying)響缸體內(nei)壁加工(gong)后的直(zhi)線(xian)度(du)(du)(du)(du)，因此建議采用(yong)鏜(tang)削(xue)-滾壓、鏜(tang)削(xue)-珩(heng)(heng)磨工(gong)藝，如直(zhi)接(jie)珩(heng)(heng)磨，則(ze)必須首先提高(gao)管(guan)(guan)材坯(pi)料的直(zhi)線(xian)度(du)(du)(du)(du)。

在允許的情況(kuang)下，液壓(ya)缸(gang)(gang)的缸(gang)(gang)體(ti)(ti)(ti)壁厚安(an)全系(xi)數盡量選(xuan)大一些，使缸(gang)(gang)體(ti)(ti)(ti)厚壁增(zeng)加，特(te)別是高壓(ya)工況(kuang)下使用的油(you)(you)缸(gang)(gang)，以減小油(you)(you)壓(ya)下的缸(gang)(gang)體(ti)(ti)(ti)變形(xing)，變形(xing)后的缸(gang)(gang)體(ti)(ti)(ti)也會引(yin)起(qi)液壓(ya)缸(gang)(gang)低速(su)爬行。
